NITED- STATES PATENT OFFICE.

GEORGE H. CARDER, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO ANDREW L. WINTERS, OF SAME PLACE.

SEAM-RIPPER.

SPECIFICATION forming part of Letters Patent No. 514,811, dated February 1 3, 1894.

' Application filed July 29, 1893- Serial No. 481,876. (No model.)

To all whom it may concern:

Be it known that l, GEORGE I-I. CARDER, a citizen of the United States, residing at Ohicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Rippers, of which the following is a description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to cutting instruments, my object being to provide a device for ripping seams of garments, cutting button holes therein, &c., and said invention consists in providing a finger cap somewhat similar to a thimble with a peculiarly shaped blade, as will be hereinafter described, and referred to in the appended claim.

The accompanying drawings illustrate my invention, and in these- Figure 1 is a perspective view of my ripper, and Fig. 2 is a view showing the preferred means of attaching the blade to the finger cap.

' In the drawings, A is a cap intended to fit upon the thumb of the operator and having sunk into its top and extending wholly across the center of the same, an outwardly curved blade B. This blade is preferably a semicircular sheet of steel, though, of course, the blade need not be a solid sheet of metal, the essential feature of the construction being that of an outwardly curved blade sunk into and extending wholly across the center of the top of the thumb or finger cap and lying in a plane at'substantially right angles to the top of the cap. Many means may be employed for securing the blade upon the cap, but I prefer that'shown in Fig. 2, in which a slot is formed in the top of the cap through which slot the blade is inserted and then upset upon the under side thereof. If desired, the 4.0

movement, while at the same time it affords no angles to catch into them or over which they may slip. The blade further being in a plane at substantially right angles to the top of the cap, the knife will always be in the line of the seam and will not pull the fabric to one side. Furthermore, my blade being shaped as specified, by resting it upon the cloth and rocking it slightly it is capable of use as a button hole cutter, an advantage possessed by neither of the patents herein disclaimed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A cutter comprising a finger cap,'and an outwardly curved blade sunk into the top thereof and extending wholly across the center of the same, said blade projecting in a plane at substantially right angles to the top; substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

. GEORGE H. OARDER.
